When Marc wasn’t looking, Scott swiped his snap circuit box. Because the back of the classroom is not so warm, Scott tried to make a really small heater for himself. He used a Nichrome wire that has a radius of 6.5 × 10 ^-4 m. The heater he makes uses of power −4 400 W when connected to a voltage source of 120 V. About how long is the wire? (Resistivity of Nichrome p= 100 x 10^-4 ohm)
